While it movably rests on the bed with one of its solid Walls p. By putting the shuttle in such position the enlargement of the shuttle is rendered possible Without entailing the above mentioned drawbacks.

lth the old construction the rear Wall of the shuttle being tlat and slanting rearwardly, the needle has to be elongated or given a longer stitching stroke in order .that the needle may pass sufficiently far behind the lower edge of said Wall to prevent the cutting ot the thread by the said edge, which would take place when the edge in course of time sharpens.

With the new arrangement of the-shut tle the rear surface n of the latter is eyln drieally curved and forms with the dat solid bottom a blunt edge n, 'which is located below the body of the shuttle and does not project beyond the rear Wall ot the latter. By reason ot this the needle z' Without elongation of the needle being required, et the ordinary stitching stroke or even at e shorter stitching stroke will pass sueiently tar beyond said edge n to allow of the thread loop g gently engaging around the curved surface n of the shuttle. Thus there is no danger of the thread being out by the edge n. Bearing now with a solid surface on the bed instead of with narrow edges the noeanse Wear is greatly reduced. `depart from that the new arrangement affords the advantage of quiet Work. lilith the old arrangement the needles had to move in jerks, to rapidly pass in due time the sharp edge of the slantihg Wall heretofore referred to. With the new arrangement however, the needles can gently more forward and back as there ie no sharp edge end therefore no danger of the thread being ent.

What claim and-desire to secure by ietteis Patent is:

In embroidering nxaeliines,v the combination with a bed or raoeway, the stitoll plate, and a stitching needle adapted to reoiproate through said stitch plate and below the raceway, of a shuttle having a curved rear surface, a flat solid bottoni bearing on said raoeway or bed and its tllling opening er.

ranged at the side directed toward the stitch plete, said solid bottom forming with the curved surface a blunt edge located below the body ot the shuttle.
